Apochromatic immersion lens for high-definition microscopy applications in water immersion, particularly for microscopic study of living objects in water immersion, is made of multiple lenses having sub-systems

摘要

The apochromatic immersion lens is made of multiple lenses having sub-systems. Five sub-systems (T1,T2,T3,T4,T5) are provided, which are cropped out from an object plane (OE). The former sub-system consists of a three layered lens component, which has the form of a meniscus deflected towards the object plane. The latter sub-system has two converging lenses (L4,L5), which are made of fluorine crown glass. The third sub-system consists of a three layered lens component and a two layered lens component, where the two layered lens component has a converging lens (L9) and a diverging lens (L10).
